BACKGROUND: The aim of this study was to compare the incidence of post-procedural acute kidney injury (AKI) and other renal outcomes in patients undergoing transapical (TA) and transfemoral (TF) approaches for transcatheter aortic valve replacement (TAVR). METHODS: All consecutive adult patients undergoing TAVR for aortic stenosis from 1 January 2008 to 30 June 2014 at a tertiary referral hospital were included. AKI was defined based on Kidney Disease Improving Global Outcomes (KDIGO) criteria...

OBJECTIVES: The aim of this study was to assess how the introduction of transcatheter aortic valve replacement (TAVR) has changed clinical practice and outcome in patients who have previously undergone coronary artery bypass grafting (CABG). BACKGROUND: A significant proportion of patients admitted for aortic valve replacement have previously undergone CABG and are therefore at increased operative risk in case of redo surgery. METHODS: In-hospital outcome data were analyzed from patients with or without previous CABG undergoing isolated surgical aortic valve replacement or TAVR in Germany from 2007 to 2013...

OBJECTIVES: The aim of this study was to investigate the efficacy and safety of intraprocedural embolic protection (EP) during transcatheter aortic valve replacement (TAVR). BACKGROUND: Randomized controlled trials (RCTs) investigating the efficacy of EP devices during TAVR were relatively underpowered. METHODS: A systematic review and study-level meta-analysis was performed of randomized controlled trials that tested the efficacy and safety of EP during TAVR...

OBJECTIVES: The study sought to assess the safety and efficacy of a minimally invasive strategy (MIS) (local anesthesia and conscious sedation) compared to general anesthesia (GA) among the largest published cohort of patients undergoing transcarotid transcatheter aortic valve replacement (TAVR). BACKGROUND: Transcarotid TAVR has been shown to be feasible and safe. There is, however, no information pertaining to the mode anesthesia in these procedures. METHODS: Between 2009 and 2014, 174 patients underwent transcarotid TAVR at 2 French centers...

BACKGROUND: A series of models have been developed to identify patients at high risk for poor outcomes after transcatheter aortic valve replacement (TAVR) to help guide treatment choices, offer patients realistic expectations of long-term outcomes, and support decision making. OBJECTIVES: This study examined the performance of the previously developed TAVR Poor Outcome risk models in an external dataset and explored the incremental contribution of geriatric domains to model performance...

BACKGROUND: Smaller transcatheter aortic valve replacement (TAVR) delivery systems have increased the number of patients eligible for transfemoral procedures while decreasing the need for transaortic (TAo) or transapical (TA) access. As a result, newer TAVR centers are likely to have less exposure to these alternative access techniques, making it harder to achieve proficiency. The purpose of this study was to evaluate the learning curve for TAVR approaches and compare perioperative outcomes...

BACKGROUND: The surgical and procedural specialties are continually evolving their methods to include more complex and technically difficult cases. These cases can be longer and incorporate multiple teams in a different model of operating room synergy. Patients are frequently older, with comorbidities adding to the complexity of these cases. Recording of this environment has become more feasible recently with advancement in video and audio capture systems often used in the simulation realm...

Transcatheter valve interventions have emerged as one of the most important developments in structural heart disease over the past 20 years. Initially, these interventions were directed at patients with severe aortic stenosis and high surgical risk; however, their applications have extended to involve other native valves' pathologies, degenerated prosthetic valves, as well as patients of lower surgical risk. In this article, we discuss the importance of cardiac imaging in transcatheter aortic valve replacement (TAVR) by exploring the current practices, guidelines, and recommendations with the supporting data...

Annular rupture presents a rare but potentially fatal complication of transcatheter aortic valve implantation (TAVI). Although it can be subtle and subclinical in presentation, most severe forms present with hemodynamic instability and represent true emergencies requiring a more invasive treatment, even conventional surgery. We present a case of successful treatment of annular rupture by left ventricular outflow tract patch and surgical aortic valve replacement.

Atrial fibrillation (AF) is a common arrhythmia in patients with aortic stenosis. When these patients are treated medically or by surgical aortic valve replacement, AF is associated with increased risk of adverse events including death. Growing evidence suggests a significant impact of AF on outcomes also in patients with aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). Conversely, limited evidence is available regarding the optimal management of this condition. This review aims to summarize prevalence, pathophysiology, prognosis, and treatment of AF in patients undergoing TAVI...

The recent literature on transcatheter aortic valve replacement (TAVR) is shedding new light on the perspective to extend this procedure to other lower risk-category of patients, leading in fact to a potential erosion of the current guidelines. Notwithstanding the warnings provided in the literature regarding the risk of severely impairing complications, unclear survival advantage and cost-inefficiency, many observational studies, especially performed in high-volume centers, support a general drive toward the recruitment of intermediate-low risk patients in the expectation of clinical advantages versus standard surgical replacement...

During the last decade transcatheter aortic valve replacement (TAVR) has been established as a treatment for patients with severe aortic stenosis, who are at particularly high surgical risk. As compared with surgical aortic valve replacement (SAVR), TAVR has been associated with lower early risk of mortality, atrial fibrillation, acute kidney injury and bleeding. Furthermore, device and peri-procedural improvements have addressed most of the initial limitations for TAVR, including the Achilles' heel, paravalvular leakage...
